(2) Cautions
1) Be sure to connect a system controller.
2) ME remote controller and MA remote controller cannot both be con-
nected to the same group of indoor units.
3) Assign to the indoor units connected to the MA remote controller ad-
dresses that are smaller than those of the indoor units that are con-
nected to the ME remote controller.
4) No more than 2 ME remote controllers can be connected to a group
of indoor units.
5) No more than 2 MA remote controllers can be connected to a group
of indoor units.
6) Do not connect the terminal blocks (TB5) on the indoor units that are
connected to different outdoor units with each other.
7) Replace the power jumper connector of the control board from CN41
to CN40 on only one of the outdoor units.
(not required if power to the transmission line for centralized control
is supplied from a controller with a power-supply function, such as
GB-50ADA)
8) Provide an electrical path to ground for the S terminal on the terminal
block for centralized control on only one of the outdoor units.
9) When the number of the connected indoor units is as shown in the
table below, one or more transmission boosters (sold separately)
are required.
To connect two transmission boosters, connect them in parallel.
(Observe the maximum number of connectable indoor units that are
listed in the specifications for each outdoor unit.)

Note1 When only the LM adapter is connected, leave SW2-1 to OFF (as it is).
Note2 LM adapters require the power supply capacity of single-phase AC 208V/230V.

are not included in the connected
indoor units

are included in the connected in-
door units
10) When a power supply unit is connected to the transmis-
sion line for centralized control, leave the power jumper
connector on CN41 as it is (factory setting).
